Some research that may be of interest to you has been done by Dr. Yossi Yovel and Dr. Argan Boonman both of Tel Aviv University. It appears that they have found non-echolocating bats do actually use echolocation they are just not to the extent of other bats. They have an article published in Current Biology.

Boonman, et al, (2014) "Non-echolocating fruit bats produce bio-sonar clicks with their wings"

Good luck with your research!!

 While much of the literature on anthropogenic noise impacts on bats is focused on foraging and use of echolocation, I think the general  body of literature on noise impacts on wildlife in general is just a pertinent. My point being, regardless of whether the noise is impacting their echolocation abilities (or how much the species is using echolocation), extreme noise would still likely impact their behavior.

You have probably seen this, but here fairly recent literature review that might be helpful: 

[Francis and Barber 2013. A framework for understanding noise impacts on wildlife: an urgent conservation priority. Frontiers in Ecology and the Environment 11: 305–313.]

I don't currently know of any studies testing anthropogenic noise impacts on specifically non-echolocating bats. However, the following road noise study was done on a Myotis bat foraging using passive listening (listening for rustling noise caused by insects moving), not echolocation. I believe it is mentioned in the Francis and Barber review as well: 

Schaub et al. 2008. Foraging bats avoid noise. The Journal of Experimental Biology 211: 3174–80.

Thank you everyone for your valuable ideas. These are all helpful from my current observation. My observation is with a non-echolocating species and a reduced activity (capture rate) was observed during the time with an extreme noise

Recently, we suggested that Eidolon dupreanum may use an incipient echolocation system (using laryngeal sound rather than wing clap sound as shown in the Boonman et al. 2014 paper) to navigate dark caves. So it seems likely that non-echolocation bats may be significantly affected by loud noise.
